What is OrderbookTrade?

Polymarket is explicitly listed as live. Kalshi is planned and Rain is integrating, so they should not be treated as equivalent current routes. A common execution interface also does not remove venue-specific funding and settlement handling.

Review how strategy outputs map to orders, inventory skew and exposure controls before production routing. For a platform launch, matching, initial capital and operational ownership are separate parts of the engagement. Published production statistics are provider-reported examples rather than an independently audited service-level agreement.

Our take on OrderbookTrade

Shared execution and matching layers give platform builders a defined integration scope. Assess availability separately from that design: access is request-based, and planned or integrating venues do not establish usable current routes.

Assessment criteria: Task usefulness, documented scope, setup clarity, and access and cost transparency.
